. UNITED STATES To ctZZ whom, it may concern: Be it known that I, JAMESW. JOHNSON, a

citizen of the United States, residing at Savj age, in the county ofFlorence and State of j South Carolina, have invented new and usefulImprovements in Plows, of which the following is a specification. Thisinvention relates to new and useful improvements in plows; and itsprimary object is to provide a device of this character having a runnerattachmentsecured thereto, 1 whereby the depth of the furrow cut by the3 plow may be readily regulated.

Afurther object is to provide a device of this character which can bequickly attached to plows of various forms and which is simple anddurable in construction.

With these and other objects in view the invention consists in providinga slotted strip having a curved arm extending from the upf per endthereof. This arm receives a bolt, j which engages. the end of a linkwhich is hinged at its lower end to a runner of peculiar construction.This runner is provided upon opposite sides with laterally-extendingflanges which are adapted to prevent the same from cutting too deep intothe ground. 3 The forward end of the runner is hinged bei tween earsextending from the lower end of the slotted strip, and the slot withinthis strip is adapted to receive a heel-pin extending I from the stockof the plow.

The invention also consists in the novel con- ;struction and combinationof parts hereinafjter more fully described and claimed, and illustratedin the accompanying drawings, showing the preferred form of myinvention, Y and in which- Figure 1 is a perspective view showing thedevice attached to a plow; and Fig. 2 is a longitudinal section throughthe strip, arm, and

link and showing the runner in elevation.

Referring to the figures by numeralsof reference,l is a plow-beam havingsuitable han- I dles 2, provided with a downwardly-extending stock 3, atthe lower end of which is secured-a shovel or plowshare 4:. A heel-pin I5 extends from the rear surface of the stock 3 and is adapted tobe'secured at any desired point within a slot 6, which extendslongitudinally within a strip 7. Ears 8 are formed PATENT OFFICE.

SPECIFICATION forming part of Letters Patent No. 681,227, dated August27, 1901. Application filed December 22, 1900. Serial No. 40,797. (Nomodel.)

therebetween is an ear 9, formed at the end of arunner 10. This runneris provided upon opposite sides with laterally-extendin g flanges 11,which are arranged in the same horizontal plane and are adapted to limitthe depth of the cut made by the runner. A curved link 12 is providedwith cars 13, which extend on opposite sides of the runner 10 at itsupper edge, and these ears are pivoted upon a pin 14, extending throughthe runner. Abolt is secured within the upper end of the curved link 12and extends into a longitudi nally extending slot 16, for1ned within acurved arm 17, projecting from the upper'end of the strip 7, beforereferred to. Suitable means, as a nut 18, is provided whereby the bolt15 can be readily secured at any desired point within the slot 16. Itwill be seen that by adjusting the bolt 15 within the slot 16 the angleof the runner to the stock 3 maybe readily changed and the depth of thefurrow cut by the plowshare is thereby regulated.

From the foregoing description it will-be seen that the device is simplein construction, durable, and cheap to manufacture, and that the samecan be readily attached to plows of various forms. By providing the slot6 within the strip 7 the attachment may be adjusted from or toward thelower end of the share.

In the foregoing description I have shown the preferred form ofmyinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without'departing from the spirit orsacrificing any of the advantages thereof, and I therefore reserve theright to make such changes as fairly fall within the scope of myinvention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination with the stock of a plow; of a strip adjustablysecured thereto, a runner hinged to the lower end of the strip,-

laterally-extending flanges to said runner, a

slotted arm extending from the strip and a link hinged to the runner andadjustably secured within the slot of the arm.

2. The combination with the stock of a plow; of a heel-pin extendingtherefrom, a strip having a longitudinally-extending slot j at the lowerend of this strip, and pivoted therein adapted to receive said pin, arunner from one end thereof, a runner hinged to the lower end of saidstrip, laterally-extending flanges upon opposite sides of the runner andlying in the same horizontal plane, and a link hinged to the upper edgeof the runner and I 5 adj ust-ably secured to the slotted arm.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES W. JOHNSON.
